> those who thought it was unethical for me to place wealth building ahead of career building.

that might well be the first time I've seen "career" and "ethical" conflated in that way. I've definitely seen the people who think you're a fool and possibly a sucker if you chase short term wealth over career stability, and there's definitely a veneer of unethicalness clinging to the notion of get-rich-quick, but I cannot understand how "establish yourself in a career" is an ethical concern.

Keep in mind that for me it was before the FAANG companies became the new evil tech overlords, and to some extent even before the Great Financial Crisis of 2008. Back then it was much easier for naive young college students or new grads to buy into that narrative of using our talents to make the world a better place through professional careers.
